Dental Sealants

Dental sealants are plastic coatings that are usually placed on the chewing (occlusal) surface of the permanent back teeth (molars and premolars) to help protect them from decay.The chewing surfaces of the molar and premolar teeth have grooves ("fissures") — that make them vulnerable to decay. These fissures can be deep and it could be difficult to clean, and can be narrower than even a single bristle of a toothbrush. Plaque accumulates in these areas, and the acid from bacteria in the plaque attacks the enamel and cavities can develop. Fluoride helps prevent decay and helps protect all the surfaces of the teeth, dental sealants provide extra protection for the grooved and pitted areas by providing a smooth surface covering over the fissured area. Dental sealants can be clear, white or have a slight tint depending upon the dental sealant used. Dental sealants have been used and have been proven to be effective since the 1970s. Many studies have shown that they are effective in helping to prevent decay on chewing (occlusion) surfaces. Dental sealants can last many years. If necessary, it is also possible to place a new dental sealant on the tooth.
